Introduction to Acids and Bases in Organic Chemistry

The first step to ranking acids and bases without Ka/pKa values is to understand the 3 common definitions of acids and bases. This video helps you understand, rather than just memorize, the Arrhenius, Bronsted-Lowry, and Lewis Definitions.

But that’s just the start, this video also shows you how to compare any 2 conjugates to determine if it’s an acid or base, especially for amphiprotic molecules which may appear ambiguous at first.

  1. Thank you for this website!!! I was worried about taking this course, but you’re website makes me feel more confident about the future.

  2. This is a great website, 10/10. You will be the reason I pass my organic chemistry final!!! So appreciative!! 🙂

  3. great videos. An Orgo 1 study group partner mentioned a Orgo 1 review video but I cant find it can you send me a link?

  4. Margaery says

    You are awesome. Thanks for making the concept so simple! You rock!

  5. Isaac Abraham says

    i was studying of the ACS ochem final guide and the explanations were not making sense. Thank you for clearing it up.

  6. Armando Dominguez says

    Oh this great. I just watched the first video, and it really clears up the three types of acid/base definitions and presents them in a way the mind can easily find the information for recall in the future.

    • Thank you for the feedback Armando. I’m glad you found this helpful because these concepts (not names, just logic behind it) will come up a LOT in the Orgo 2 upcoming reactions
